Magnetosphere-Ionosphere-Thermosphere Coupling during Disturbed Times

Session ID#: 157095

Session Description:
Determining the effects of energy deposition and transport, and momentum exchange across regions and different spatial and temporal scales during disturbed times such as storms and substorms is an important objective in the M-I-T system. Coupling across multiple scales is also a critical challenge since observational and modeling methodologies for bridging different scales do not presently exist. This session solicits presentations on a wide range of coupling processes in the M-I-T system from global to local processes. Relevant topics include (but are not limited to) (1) density structures and temperature gradients (polar cap patch, cusp, plume, trough, irregularities); (2) convection (fast flows, SAPS, penetration electric field) and currents; (3) energy transfer and deposition by precipitation, conductivity, aurora, and heating; (4) ion-neutral interaction (thermospheric density and wind) and (5) coupling and feedback into the magnetosphere (including waves and instabilities). Discussions by all means of observations, modeling and data science are encouraged.
